FEED-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 658,245, dated September 18, 1900.

Application iiled September 5, 1899. Serial No. 729,495. (No model.)

fo all whom it may concern:

Be it known that I, Louis MARIE GABRIEL DELAUNAY-BELLEVILLE, a citizen of the Re! public of France,residing at St. Denis, France,

have invented certain new and useful Improvements in Feed Water Heaters' and Steam-Purifiers for use in Connection with Steam-Generators, of which the following is a specification. v

The object of this invention is to provide a combined steam and feed-water collecting and purifying apparatus for use with steamboilers, the internal parts of which apparatus can be connected and disconnected with great facility, and it is therefore specially applicable for use with marine boilers.

I will describe the invention with reference to the accompanying drawings, in which- Figure lis a longitudinal vertical section on the line A A B Bof Fig. 2. Fig. 2 is a transverse section on the line C Cof Fig. l. Fig. 3 is a front elevation. Fig. 4 is a longitudinal horizontal section onthe line D D D E E EE F F F, Figs. l and 3. Fig. 5 is a transverse vertical section on the line G G, Fig. l. Fig. 6 is a transverse section on the line H H of Fig. 1. Fig. 7 is a broken plan showing the steam-inlet. Fig. 8 is a view in front elevationshowing the application of the invention to a steam-boiler.

The body a of the apparatus is cylindrical and its ends o (which should be made of steel) are each provided with a check-valve in the box b, which the feedwater enters through a pipe d, it passing into the interior of the apparatus through the pipes e. Each end Z7 has also fitted to it a water-return branch pipe, nozzle, or jet f, through which the feed-water flows into the boiler. In each end above the valve-box c and the nozzle or jetf is provided a hole g for inspection, cleaning, and connecting or disconnecting purposes. These holes are closed byV means of tight doors or closing devices of any suitable description. Two similarly-closable holes h hv are provided in the side of the body a, which body is fitted at its. lower part `with jets or branch pipes 7l, to the lower ends of which are coupled the steam-producing or vaporizing tubes of the boiler, the upper ends extending into the interior of the apparatus, as shown. Above the upper orifices of the l pipes il there is arranged a dome or inverted trough k, extending over the whole ofthe pipes z', its object being to deflect downward themixture of water and steam, which is forced from the boiler into the apparatus through the pipes 1,'. This dome or inverted trough 7c is made in parts secured at about the center of the apparatus to a .support m, common to bothand consisting of a bent metal plate attached to the body a in any con-A venient manner. In the drawings, Fig. 2, I have shown themeans of attachment as consisting of two angle-pieces fn, n, riveted to the port s, riveted to the body-piece r, which rests upon a support s, riveted to the body part et, the bolts t serving to retain the dome 'or inverted trough in position. Each half of the dome or inverted trough lt consists of two parts connected together by a plate riveted to one and secured to the other by bolts u. On eitherside of the interiorof the body part a and extending from end to end thereof are two bent metal plates/U, Fig. 6, riveted to the body a and intended to prevent the water deflected down bythe dome or inverted trough Ic from rising again along the walls.

In thel center of the top part of the apparatus and above the support fm is tightly riveted the steam-supply chamber w, constructed, preferably, of stout steel. Qcis the steamoutlet, to which is secured, by nuts on `the screw-bolts y, the end of the steam-supply pipe. The steam enters the chamber w through two steam-inlet tubes z, provided with perforations, as shown in Fig. 7. These tubeszare open at one endg-viz., the end at which they communicate with the chamber lwand they are provided with conical endl pieces or couplings, whereby they are tightly' secured in the walls of the chamber w.- The opposite ends of these tubes z are closed, they being each provided with a flange, such as 1,

IOO

which are secured by bolts 2 to angle-pieces 3, riveted to the body part a. The joint between the open end of each of the tubes 2 and the walls of the chamber w is kept tight by screwing home the bolts 2.

The mixture of water and steam which the boiler discharges into the apparatus through the pipes or jets @I meets the dome or inverted trough k,which deectsitdownward. The Water collects in the lower part of the apparatus while the steam rises to the upper part and enters the steam-supply chamber w through the perforations in the tubes c, whence it is supplied to the engine. v The feed-water may come direct from a tank or any other suitable source of water-supply. The pipes e, which are bent to a point in a direction parallel with the axis of the apparatus, are both arranged on the same side of the pipes or jets t' and divide the feed-water into two currents flowing in opposite directions to each other and which at their meeting,r point are so deflected as to pass over to the other side of the said jets z' and return toward the ends b, mixing, as they do so, with the water forced down by the dome or inverted trough 7c and then passing through the jetsfinto the vaporiZing-tubes.

In apparatus constructed or arranged according to my invention the internal parts can be disconnected and removed and replaced and connected with great facility and without disconnecting or shifting the apparatus itself, because they are retained in place by a small number of bolts or fastenings, which are situated in the vicinity of the inspection-holes.

If either half of the dome or inverted trough 7c when detached can-not be sufficiently inclined to admit of its removal through the correspondinginspection-hole, the fastenings u can be removed and the halt` be again divided. l

The principal object of constructing the support m in the shape of an inverted cup is to enable it to intercept the current of feedwaterif there should be only one inlet for feed-water; but I prefer to use two such inlets, as at d c e in the drawings, so that the feed-water can pass unimpeded into the apparatus, even should the temperature of this water happen to be at the time higher than that of the steam.

All accessory parts and details may be varied according to requirements without departing from the nature of my invention.

Having now particularly described and ascertained the nature of my invention and in what manner the same is to be performed, I declare that what I claim is- 1. Apparatus of the character described, comprising a chamber, adapted to conduct the feed-water to the boiler and having steampipe connection with the boiler, a water and steam detlector arranged in said chamber, above the feed-water line and contiguously to the upper delivery ends of the pipes of said steam-pipe connection, said pipes also extending above the feed-water line, whereby the water and steam entering through said pipes are deflected or diverted, the water being directed into the feed-water chamber, and the steam passing oif to the steam-supply, substantially as set forth.

2. Apparatus of the character described,`

comprising a chamber adapted to conduct the feed-water to the boiler and having steampipe connection with the boiler, a water and steam deiiector arranged in said chamber, above the feed-water line and contiguously to the upper delivery ends of the pipes of said steam-pipe connection, said pipes also extending above the feed-water line, the stcam-supply chamber arranged in the upper part of said rst referred-to chamber, above said deiector, and perforated pipes connected to said steam-supply chamber, substantially as set forth.

3. Apparatus of the character described comprising a cylinder or chamber, having feed-water-pipe connection and steam-pipe connection with the boiler, the feed-water pipes extending into the lower .part of said cylinder or chamber, in opposite directions, the deflector, inverted-trough shape and arranged above the feed-water line, the steamsupply chamber arranged in the upper part of said cylinder, and the perforated pipes connected to said steam-supply chamber, the pipes of said steam-pipe connection also extending above said feed-water line, with their upper or delivery ends arranged contiguously to said deflectors, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
